No, that's not true. The file system can be stored in the RDB area of the harddisk, so it can easily be upgraded without hardware change.
Thomas,
Can you explain what storing it in the RDB means? I know what the RDB is, but, how do you store the filesystem there? I have heard this said many times, "install the FS on the RDB," but, I had, I guess, always assumed that when partitioning the drive, it was doing as such. Please give instruction on how to do this on both 3.1 and 3.9.
Thank you very much,
Kirk
